Thanks DobbiebrotherThe plants will be fine so long as you keep them in about the same timing for putting them in the dark.
All they need to keep in flower is enough light to keep them thinking it day time (just a cloudy day).
If kept like that for many days you will see them stretch more than they should as they try to reach for the weaker light.
But short term will show no ill effects, and once power is back on they'll chug along at full speed again under your grow light/s.
Looking good ADT, love the fat leaves on the PMs.
Is that danksters pm?
